Every year, millions of tonnes of perfectly good food are wasted around the world because people aren't sure it's still fresh. To cut down on this, researchers at Fraunhofer are developing an infrared pocket scanner that will let food handlers determine if a food item has gone bad.

It's all very well and good, printing color graphics onto sheets of paper. However, what happens if you want to print them onto a wall, a piece of wood, an item of clothing, or anything else that can't be fed through a desktop printer? Well, that's where the PrintBrush XDR comes in.

Our drones are pretty handy, but nature’s drones – bees – are far more efficient. Rather than building our own from scratch, researchers at the University of Washington have created tiny suites of sensors that bees can wear like backpacks, to help gather data from their environment.

Electromagnetic pulse (EMP) weapons might be a staple of movies and video games, but they pose a very real threat. Sandia National Laboratories has developed a "friendly" EMP generator to make sure military and civilian equipment can withstand such potentially devastating bursts of energy.

Engineers from MIT and the University of Colorado have developed a new microfabrication technique and used it to produce the smallest 3D transistors ever made, measuring about a third the size of the current leading commercial products.

Eye-tracking systems certainly would add a lot to augmented reality glasses, but their integration into such eyewear has been limited because they require so much power. That said, scientists have now developed eye-tracking glasses powered by nothing but onboard solar cells.

The electronics inside consumer gadgets are often miniaturized versions of bigger components – like phone cameras, for instance – and that applies to the gyroscopes used to help a device orientate itself in 3D space. Now scientists have worked out a way of making these gyroscopes much, much smaller.
